Re: 431RWHP A4 346 Conrats to Tom and LS1Speed - great numbers. I've been by Tom's shop a few times when I lived in Chicago and actually met Tom. He seems to be a down to earth, no-nonsense kinda guy. If I still lived up there, LS1Speed would be performing my go fast mods. 
Re: 431RWHP A4 346" Thanks for sharing Speed Inc.!
The cool thing about when they post dyno numbers they install so many different combinations of heads and cams that we get a lot of fair and unbiased numbers off that dyno.

Re: 431RWHP A4 346" nice combo.
isn't that very lean? i'm curious to see if you will ping (KR) while on the track (dynojet doesn't create enough load to simulate true road/race conditions). atap your drag strip runs.

Re: 431RWHP A4 346" Just goes to show Speed Inc rules. 
Only had a few things installed by them but very happy with there service. Getting a appointment is another story. You guys are too good and busy. 
Can you use those heads with that cam on a stock short block? Im planning on heads and cam first then your 346 shortblock later. But before that im gonna have to have you guys get me a new 4L60E my stocker is going south fast.
